I used to use the RPi 2b and had no problems with my Xbee codes but this new RPi3 is killing me. I can not read from my XBee model S2 Pro anymore.
Following instructions from other forums I have changed the TTY to S0 with
SERIALPORT = '/dev/ttyS0'
I have changed the UART in /boot to:
enable_uart=1
and in rasps-config I have enabled the login shell on serial. My simply code is as follows:
import serial, time, datetime, sys
from xbee import XBee
#from xbee import ZigBee
#import subprocess
#import pprint
#import MySQLdb
#import chat
SERIALPORT = '/dev/ttyS0'
BAUDRATE = 9600
ser = serial.Serial(SERIALPORT, BAUDRATE)
xbee = XBee(ser)
print 'Starting Up XBee Monitor'
# Continuously read and print packets
while True:
try:
response = xbee.wait_read_frame()
print response
except KeyboardInterrupt:
break
ser.close()
An so my error is also as follows:
Starting Up XBee Monitor
Traceback (most recent call last):
File "wetter.py", line 21, in <module>
response = xbee.wait_read_frame()
File "/usr/local/lib/python2.7/dist-packages/xbee/base.py", line 412, in wait_read_frame
frame = self._wait_for_frame()
File "/usr/local/lib/python2.7/dist-packages/xbee/base.py", line 130, in _wait_for_frame
if self.serial.inWaiting() == 0:

return self.in_waiting

s = fcntl.ioctl(self.fd, TIOCINQ, TIOCM_zero_str)
IOError: [Errno 5] Input/output error
I am simply not having any luck with this. I am using Jessie Lite and Python 3. Does anyone have any other ideas?
